SANDlNG-BOX FOR CARS.

SPECIFICATION forming part of Letters Patent No. 501,722, dated July 18, 1893.

Application filed March l0, 1893. Serial No. 465.474. (No model.) l

To @ZZ whom it may concern:

Be it known that I, JOHN J. KENNELLY, a citizen of the United States, and a resident of New York, in the county and State of New York, have invented a certain new and useful Improvement in Sanding-Boxes for Street- Cars and other Vehicles, of which the following is a specification.

My invention relates to improvements in 1o sanding boxes for cars on tram and street lines. In all cases where thecar is a self mover, as in the case of electric-motor cars,

or compressed air motors and numerous oth ers, the slipping of the wheels on the rails in I5 frosty, sleety or snowy weather is a serious matter, and it is the especial object of my invention to provide a device on such cars for sanding the rails to increase the friction, which device shall be small and compact zo enough to be readily worked by the motor man, (preferably by his foot, but by hand if so desired.) It is also the purpose of my invention to introduce into the box devices for picking and 2 5 loosening the sand, operated by the same action as feeds the sand to the rails.

Referringto the drawings which accompany the specification to aid the description, Figure l is a representation of the device applied to 3o a street car. Fig. 2 is an enlarged sectional detail of the device for operating the sanding box by the foot of the motor man. Fig. 3 is a view of the same from below. Fig. 4 is a plan view of the sanding box. Fig. 5 is an 3 5 elevation of the same with one side removed,

to show the interior. Fig. 6 is a representation of a modification of the device. Fig. 7 is a plan view of sanding box of the same.

The car, A, is .of any usual description,and 4.o preferably has two of the sanding apparatus each placed in front of the diagonally opposite wheel of each pair of wheels.

The sanding box, B, is secured to the bottom of the car in front of its proper wheel, as seen in Fig. l, and an upper part, B', rises above the iioor nearly to the seats, so as to hold a considerable quantity of sand. The

opposite sides of the box preferably have little ledges, a., a, to make a good fit with the bottoms, CZ, CZ', that are pivoted on the axles, f,f, which turn in bearings in the box. Said bottoms, CZ, CZ', are of such dimensions as when horizontal, to fill the area of the box, and the said bottoms, CZ, CZ', carry vertical arms, CZ2, d3, with pointed or bladed upper ends, to prick the sand, as will be described hereinafter.

The said axles, f, f', of the bottoms, CZ, d',

sleeve, o, is preferably enlarged downwardly,

as shown, to facilitate the removal of dirt. Under the head, n, of said post, n, is a trip, p, having one arm, p', somewhat higher than the other p2, and pivoted at p3, so that the arm, hp', can when desired be turned under the head, n', to preventdepressing the post, n. `A spring, q, is arranged to retract the bell crank lever, Z, after the same has been acted on by the post, fn. r, is a flange plate to aid in securing the sleeve, p, and frame m to the bottom of the platform.

The operation is as follows: Suppose the motor man wishes to sand the track, then he steps on the top of the post, n, at the front end of the car, thereby depressing the bell crank lever, Zo, andY drawing the connecting rod, j, to the left. This oscillates the lever, h, and rotates the gear sector, g, and tips the bottom, CZ. VAt the same time the geared sec'- tor, g', tips the bottom, CZ', and the sand runs out over the rail. While the bottoms, CZ, CZ', are tipping, the arms, d2, d3, and their upper blades work and prick the sand, lso as to loosen it if it is caked. By Working his foot rapidly on the post, n, the motor man is thus able to readily loosen the sand. When the foot is removedfrom the post, n, the spring, q, pushes the bell crank lever, lc, to its original position .and the bottoms, CZ, CZ', are thus again turned horizontal to prevent the escape of more sand. In Figs. 6 and 7, I show a modilication of my device, wherein I use a link, l, to operate the bottoms, cl, d', in place of the aforesaid geared sectors. The bottoms, d, d', carry the blades, 3, 3, that are preferably crossed, and have a shearing action on the sand. Said link, 1, is pivotally attached as shown, at the lower ends of the arms, h', h2. I also preferl to use a short link, 2,between the link l, and the connecting rod,j, which rod, j', is connected at its other end with the bell crank lever, Z, that is operated by the post'n, as

before described. q', is a spring to retract the bell crank lever, when the motor mans foot is lifted from the post.

The operation will be evident from the explanation given in connection with Figs. l to 5, and does not require separate description.

The sanding box, l5, can of course be made in any4 suitable manner, but I- prefer as a with thebox fram-e, b', composed of two parts, having flanges, b2, with bolt holes on them-eeting edges ofeach post.

Now, havingdescribed my improvement, I claim as my invention- 1. The combination, in sanding boxes, of pivoted bottoms in the boxes, arms on said bottom-sada-p-ted to-prick the sand, geared sectors on the pivotsof thebottoms, and devices Y' at one arm to a device for tripping the bottoms and having av socket in the other arm,

and a removable tread adapted to bea-r in said socket and be removed therefrom at will, substantially as described.

5. In a sanding box, the combination with tipping bottoms, of a connecting rod adapted to trip the bottoms, a bell-crank lever having one arm connected with said rod, a sleeve fixed onthe car adj-acentto the other arm of :the leverand dared downwardly, and a re movable tread adapted to bear on said other arm of the lever and guided in said sleeve,

substantially as described.

6. In a sanding box, the combination of a removable tread, a downwardly flared sleeve vfixed on lthe-car and adapted to guide said tread, a bell-crank lever having one arm engaging the end of the tread and the other arm actuated by a spring and connected with a rod for operating the bottoms, snbstantiall y p asdescribed. cheap and effective construction to form it 7. rPhe combination, in a sanding box of a `connecting rod` adapted to operate thebottoms, a bell-crankv lever having one armcon-- `nected withk said rod and also actuating-a spring, a treadv adapted to'engagethe other `arm of the lever and remo-vab-lyfguidedin a downwardly daring sleeve, andv adog p-ivoted adjacent to the tread and adaptedv to enga-ge the head thereof, substantially as described.

8, A sanding box made intwo parts, each part forming one half of a body-and'` of a downwardly projecting nozzle therefrom and ;being provided with anges and bolt holes at the meeting faces forfastenin g the twoparts together, and each of said parts` also being `,provided with flanges at the upper end for securing the box to a-car, substantially asdescribed;

In testimony that I claim the foregoing as my invention I have signed my name, in p-res- 'ence ofgtwowitnesses, this 27th da-yof'Janu- -Elfiyj 1893.
